Collaborative grounding is distinct from perceptual (or symbol) grounding [1]}, [2]}, [3]}, [4]}. The perceptual grounding literature deals with capabilities enabling symbols to be linked with perceptions, and is rooted in situationally
relevant modalities such as vision. Collaborative grounding, on the other hand, deals with the
dynamics of conversation
(the ongoing exchange of speaker and hearer roles)
and is rooted in situationally relevant aspects of
socioperception.
Alikhani and Stone alikhani:2020 note several basic mechanisms that contribute to collaborative grounding, including those for dealing with joint attention [5]}, [6]}, [7]}, engagement [8]}, [9]}, turn taking and incremental interpretation [10]}, [11]}, [12]}, [13]} corrections and clarifications [14]}, [15]} and dialogue management [16]}, [11]}. These mechanisms have been studied for different kinds of applications [18]}, [19]}, [20]}.
Both collaborative and perceptual
grounding are important (all relevant
modalities are potentially important) and
in this paper we bring them together under an umbrella we call grounded clarification.
